Abstract
PURPOSE: To provide the titled heat exchanger having a small radius of bend and excellent in cooling efficiency by a method wherein the fins provided with cut lines leaving both end faces uncut are laminated, then hairpin pipes are inserted into the laminate and fixed in situ, thereafter the fins are cut up along the cut lines and are rotated with the hairpin pipe as a center.
CONSTITUTION: The fins 1 provided with the cut line 21 are laminated, the hairpin pipes 2 are inserted into the laminate, and the pipes are expanded to fix the fins 1 and the pipes 2 to each other. Then a bend pipe 20 fitted in the straight pipe part 16 of a hairpin pipe 15 bridged over the cut line 21 is removed, and a bend pipe 3 is fitted by welding. Both ends of the cut line 21 are cut 19, and the fins 2 are rotated with the straight pipe part 16 as an axis. Then the hairpin pipes 15 and 22 are connected to each other by a bend pipe. Accordingly, a rectangularly bent heat exchanger can be obtained with a small radius of bend and without sacrificing the cooling performance.
